One of my 50's Faves
This is a terrif little thriller;
the creature is horrifying and unstoppable. The suspense is the Best !
Good cast and moves quickly.I Like the noirish lighting and the b\w is most effective.
And purported to be a direct inspiration for Ridley Scott's "Alien" (although the authors said a comic book story called "Seeds Of Venus" was actually what inspired them).
The last line is something, too.
"Another name for Mars is death."
